Effective September 7, 2010 (the Effective Date), the Columbia funds, Columbia
Acorn funds and RiverSource funds (including the Seligman and Threadneedle
branded funds) share the same policies and procedures for investor services, as
described herein. For example, for purposes of calculating the initial sales
charge on the purchase of Class A shares of a fund, an investor or financial
advisor should consider the combined market value of all Columbia, Columbia
Acorn, RiverSource, Seligman and Threadneedle funds owned by the investor. For
details on this particular policy, see below in this Supplement the restatement
of the section "RIGHTS OF ACCUMULATION (ROA)."

For purposes of this Supplement, the Columbia funds and Columbia Acorn funds and
portfolios are collectively referred to as the Columbia funds. The RiverSource
funds (including the Seligman and Threadneedle branded funds) are collectively
referred to as the RiverSource funds. Together the Columbia funds and the
RiverSource funds are referred to as the Funds. On September 27, 2010, certain
of the RiverSource, Seligman and Threadneedle funds will change their names to
reflect the Columbia brand. Regardless of the name change to a RiverSource fund,
a Seligman fund or a Threadneedle fund, each of these Funds should be regarded
as a RiverSource fund, Seligman fund or Threadneedle fund (per their current
name) and should not be considered a "Columbia fund" for purposes of this
Supplement.

The following terms have the following meaning: Columbia Management or the
investment manager means Columbia Management Investment Advisers, LLC, the
Transfer Agent means Columbia Management Investment Services Corp., and the
Distributor means Columbia Management Investment Distributors, Inc. In addition,
as used throughout this Supplement, the terms "selling agent" and "servicing
agent" refer to the financial intermediary that employs your financial advisor.
Selling and/or servicing agents include, for example, brokerage firms, banks,
investment advisors, third party administrators and other financial
intermediaries.

includes the Seligman and Threadneedle branded funds) and their status as of the
Effective Date (or other date, as noted below) are as follows:

* Relates to RiverSource S&P 500 Index Fund.
** Class R3, R4 and Class R5 shares are closed to new investors as of the close
of business on December 31, 2010, as further described below in this Supplement.
*** For RiverSource Cash Management Fund, Class Y shares will be converted to
Class Z shares on or about August 27, 2010. For RiverSource Retirement Plus
Funds, Class Y shares will be renamed as Class Z shares on the Effective Date.

Accordingly, on the Effective Date, the RiverSource funds will offer the
following share classes: Class A, Class C, Class I, Class R, Class W and Class Z
shares, and will offer Class R3, Class R4 and Class R5 until their close
effective at the close of business on December 31, 2010.

The following changes are effective on the Effective Date:

The following information replaces the information under and including the
captions "Buying and Selling Shares -- Description of Share
Classes -- Investment Options -- Classes of Shares -- Investment Options
Summary" (which is renamed as "Choosing a Share Class -- Comparison of the Share
Classes").

Not all Funds offer every class of shares. The Fund offers the class(es) of
shares set forth on the cover of this prospectus (the Fund may also offer other
classes of shares through a separate prospectus). Each share class has its own
investment eligibility criteria, cost structure and other features. You may not
be eligible for every share class. If you purchase shares of the Fund through a
retirement plan or other product or program sponsored by your financial
intermediary, not all share classes may be made available to you. The following
summarizes the primary



features of the Class A, Class C, Class I, Class R (formerly Class R2), Class
R3, Class R4, Class R5, Class W and Class Z shares (but, as stated above, the
Fund offers only the classes of shares set forth on the cover of this
prospectus). Although as of the Effective Date Class B shares are closed to new
and existing investors, information relating to Class B shares is included in
the table below because certain qualifying purchase orders for Class B shares
are permitted, as described below. When deciding which class of shares to buy,
you should consider, among other things:

- - The amount you plan to invest.

- - How long you intend to remain invested in the Fund.

- - The expenses for each share class.

- - Whether you may be eligible for reduction or waiver of sales charges when you
  buy or sell shares.

Each investor's personal situation is different and you may wish to discuss with
your financial intermediary which share class is best for you. Your authorized
financial intermediary or financial advisor can help you determine which share
class(es) is available to you and to decide which class of shares best meets
your needs.

* For money market Funds, new investments must be made in Class A, Class I
(available as a new investment only to the Funds (i.e., Fund-of-Fund
investment), Class R (available as a new investment only to investors in the
Distributor's proprietary 401(k) products), Class W or Class Z shares of the
Fund. The money market Funds offer other classes of shares only to facilitate
exchanges with other Funds offering such share classes.

** Unless contrary instructions are received in advance by the Fund, any
purchase orders (except those submitted by a selling and/or servicing agent
through the National Securities Clearing Corporation (NSCC) as described in more
detail



below) that are initial investments in Class B shares or that are orders for
additional Class B shares of the Fund received from existing investors in Class
B shares, including orders made through an active systematic investment plan,
will automatically be invested in Class A shares of the Fund, without regard to
the normal minimum initial investment requirement for Class A shares, but
subject to the applicable front-end sales charge. Your selling and/or service
agent may have different polices, including automatically redirecting the
purchase order to a money market fund.

*** The minimum initial investment requirement is $5,000 for RiverSource
Disciplined Small Cap Value Fund, RiverSource Floating Rate Fund and RiverSource
Inflation Protected Securities Fund, and $10,000 for RiverSource 120/20
Contrarian Equity Fund, Threadneedle Global Extended Alpha Fund and RiverSource
Absolute Return Currency and Income Fund.

(+) There is no investment limit on Class C shares purchased by employee benefit
plans created under section 401(a), 401(k), 457 and 403(b), and qualified
deferred compensation plans that have a plan level or omnibus account maintained
with the Fund or the Transfer Agent and transacts directly with the Fund or the
Transfer Agent through a third party administrator or third party recordkeeper.

(a) See below and the prospectus (as supplemented hereby) for more details on
the eligible investors and minimum initial and subsequent investment and account
balance requirements of these share classes.

(b) See below and the prospectus (as supplemented hereby) for information about
certain exceptions to these sales charges.

(c) The maximum applicable distribution and/or shareholder service fees. Because
these fees are paid out of Fund assets on an on-going basis, over time these
fees will increase the cost of your investment and may cost you more than paying
other types of distribution and/or shareholder service fees. The Distributor has
voluntarily agreed, effective April 15, 2010, to waive the 12b-1 fees it
receives from Class A, Class C, Class R (formerly Class R2) and Class W shares
of RiverSource Cash Management Fund and from Class A, Class C and Class R
(formerly Class R2) shares of RiverSource Government Money Market Fund.
Compensation paid to broker-dealers and other financial intermediaries may be
suspended to the extent of the Distributor's waiver of the 12b-1 fees on these
specific share classes of these Funds. See "DISTRIBUTION AND SERVICE FEES" below
for more information.

(d) There is no CDSC on Class A shares of the money market Funds or RiverSource
S&P 500 Index Fund.

(e) See below for more information on the timing of conversion of Class B shares
to Class A shares. Timing of conversion and CDSC schedule will vary depending on
the Fund and the date of your original purchase of Class B shares.

(f) See "PLAN ADMINISTRATION FEE" below for more information.

(g) Shareholders who opened and funded a Class R3, Class R4 or Class R5 shares
account with a Fund as of the close of business on December 31, 2010 (including
accounts once funded that subsequently reached a zero balance), may continue to
make additional purchases of the share class, and existing Class R3, Class R4 or
Class R5 accounts may continue to allow new investors or participants to be
established in their Fund account. See below for more information on eligible
investors in Class R3, Class R4 and Class R5 shares and the closing of these
share classes.



The following information replaces the information under "Distribution and
Service Fees" (if applicable):

Pursuant to Rule 12b-1 under the 1940 Act, the Board has approved, and the Funds
have adopted, distribution and/or shareholder service plans which set the
distribution and/or service fees that are periodically deducted from the Fund's
assets. These fees are calculated daily, may vary by share class and are
intended to compensate the Distributor and/or eligible selling and/or servicing
agents for selling shares of the Fund and providing services to investors.
Because the fees are paid out of the Fund's assets on an ongoing basis, they
will increase the cost of your investment over time.

The table below shows the maximum annual distribution and/or service fees (as an
annual percent of average daily net assets) and the combined amount of such fees
applicable to each share class of the RiverSource funds (including the Seligman
and Threadneedle branded funds).

(a) Fees amounts noted apply to all Funds other than RiverSource Cash Management
Fund, which for each of Class A and Class W shares, pays distribution and
service fees of 0.10% and for Class C shares pays distribution fees of 0.75%.
The Distributor has voluntarily agreed, effective April 15, 2010, to waive the
12b-1 fees it receives from Class A, Class C, Class R (formerly Class R2) and
Class W shares of RiverSource Cash Management Fund and from Class A, Class C and
Class R (formerly Class R2) shares of RiverSource Government Money Market Fund.
Compensation paid to broker-dealers and other financial intermediaries may be
suspended to the extent of the Distributor's waiver of the 12b-1 fees on these
specific share classes of these Funds.
(b) Fees amounts noted apply to all Funds other than RiverSource Cash Management
Fund, which pays distribution fees of up to 0.75% and service fees of up to
0.10%, for a combined total of 0.85%. Effective after the close of business on
September 3, 2010, Class B shares will be closed to new and existing investors.
(c) The RiverSource funds have a distribution and shareholder service plan for
Class R shares, which, prior to the close of business on September 3, 2010, were
known as Class R2 shares. For RiverSource funds Class R shares, the maximum fee
under the plan reimbursed for distribution expenses is equal on an annual basis
to 0.50% of the average daily net assets of the Fund attributable to Class R
shares. Of that amount, up to 0.25% may be reimbursed for shareholder service
expenses.

(d) The shareholder service fees for Class R3 and Class R4 shares are not paid
pursuant to a 12b-1 plan. Under a plan administration services agreement, the
Fund's Class R3 and Class R4 shares pay for plan administration services,
including services such as implementation and conversion services, account set-
up and maintenance, reconciliation and account recordkeeping, education services
and administration to various plan types, including 529 plans, retirement plans
and health savings accounts.



The distribution and/or shareholder service fees for Class A, Class B, Class C,
Class R (formerly Class R2), R3 and Class W shares, as applicable, are subject
to the requirements of Rule 12b-1 under the 1940 Act, and are to reimburse the
Distributor for certain expenses it incurs in connection with distributing the
Fund's shares and directly or indirectly providing services to Fund
shareholders. These payments or expenses include providing distribution and/or
shareholder service fees to selling and/or servicing agents that sell shares of
the Fund or provide services to Fund shareholders. The Distributor may retain
these fees otherwise payable to selling and/or servicing agents if the amounts
due are below an amount determined by the Distributor in its discretion.

For RiverSource fund Class A, Class B and Class W shares, the Distributor begins
to pay these fees immediately after purchase. For RiverSource fund Class C
shares, the Distributor pays these fees in advance for the first 12 months.
Selling and/or servicing agents also receive distribution fees up to 0.75% of
the average daily net assets of RiverSource fund Class C shares sold and held
through them, which the Distributor begins to pay 12 months after purchase. For
RiverSource fund Class B shares, and, for the first 12 months following the sale
of RiverSource fund Class C shares, the Distributor retains the distribution fee
of up to 0.75% in order to finance the payment of sales commissions to selling
and/or servicing agents, and to pay for other distribution related expenses.
Selling and/or servicing agents may compensate their financial advisors with the
shareholder service and distribution fees paid to them by the Distributor.

IF YOU MAINTAIN SHARES OF THE FUND DIRECTLY WITH THE FUND, WITHOUT WORKING
DIRECTLY WITH A FINANCIAL ADVISOR OR SELLING AND/OR SERVICING AGENT,
DISTRIBUTION AND SERVICE FEES MAY BE RETAINED BY THE DISTRIBUTOR AS PAYMENT OR
REIMBURSEMENT FOR INCURRING CERTAIN DISTRIBUTION AND SHAREHOLDER SERVICE RELATED
EXPENSES.

Over time, these distribution and/or shareholder service fees will reduce the
return on your investment and may cost you more than paying other types of sales
charges. The Fund will pay these fees to the Distributor and/or to eligible
selling and/or servicing agents for as long as the distribution and/or
shareholder servicing plans continue in effect. The Fund may reduce or
discontinue payments at any time. Your selling and/or servicing agent may also
charge you other additional fees for providing services to your account, which
may be different from those described here.

For all Funds except RiverSource S&P 500 Index Fund, the following information
replaces the information under the section heading "Plan Administration Fee":

Class R3 and Class R4 shares pay an annual plan administration services fee for
the provision of various administrative, recordkeeping, communication and



educational services. The fee for Class R3 and Class R4 shares is equal on an
annual basis to 0.25% of average daily net assets attributable to the class.

For RiverSource S&P 500 Index Fund, the information under and including the
section heading "Plan Administration Fee" is hereby deleted.

The following information replaces the information under "Determining which
class of shares to purchase -- Class A, Class B and Class C shares":

CLASS B SHARES CLOSING
Currently, Class B shares for RiverSource Absolute Return Currency and Income
Fund, RiverSource Floating Rate Fund, RiverSource Inflation Protected Securities
Fund, RiverSource Intermediate Tax-Exempt Fund, RiverSource Limited Duration
Bond Fund and RiverSource Short Duration U.S. Government Fund are closed to new
investors and new purchases.

As of the Effective Date, the Fund's Class B shares will be closed to new
accounts and additional purchases by existing Class B shareholders. As of the
Effective Date, shareholders owning Class B shares may continue to hold those
shares (and any Class B shares acquired after that date pursuant to an exchange
or distribution reinvestment) until they automatically convert to Class A shares
under the Fund's existing conversion schedule. Existing shareholders of Class B
shares may continue to exchange their Class B shares for Class B shares of other
Funds that offer Class B shares for exchange. Existing Class B shareholders may
also continue to add to their accounts through the reinvestment of dividends and
capital gain distributions until their conversion to Class A shares.

On and after the Effective Date, any purchase orders for Class B shares that are
initial investments or that are orders for additional shares, including orders
made through an active systematic investment plan (other than a permitted
exchange or a distribution reinvestment, or purchase orders submitted by a
financial intermediary through the National Securities Clearing Corporation
(NSCC) as described in more detail below), will automatically be invested in
Class A shares of the Fund, without regard to the normal minimum initial
investment for Class A shares, but subject to the front-end sales charge that
generally applies to Class A shares. By being invested in Class A shares
(instead of Class B shares), the actual amount invested in the Fund will be
reduced by the amount of any applicable front-end sales charge. For purposes of
determining the applicable Class A front-end sales charge, the value of a
shareholder's account will be deemed to include the value of all applicable
shares in eligible accounts, including Class B shares. Please see RIGHTS OF
ACCUMULATION (ROA) below for more information. Your financial advisor or selling
and/or servicing agent may have different policies not described here, including
a policy to reject purchase orders for Fund Class B shares on and after the
Effective Date or to automatically invest the purchase amount in a money market
fund. Please consult your financial advisor or selling and/or servicing agent to
understand their policy.



Additional purchase orders for a Fund's Class B shares by an existing Class B
shareholder, submitted by such shareholder's financial advisor through the NSCC,
will be rejected due to operational limitations of the NSCC. Investors should
consult their financial advisor if they wish to invest in the Fund by purchasing
a share class of the Fund other than Class B shares.

Dividend and/or capital gain distributions from Class B shares of a Fund will
not be automatically invested in Class B shares of another Fund. Such dividend
and/or capital gain distributions from Class B shares of a Fund will be
reinvested in Class B shares of the same Fund that is making the distribution.

On and after the Effective Date, the Repurchase privilege (described below under
Repurchases) will no longer be offered for Class B shares. However, shareholders
who redeem Class B shares (subject to the imposition of any applicable
contingent deferred sales charge (CDSC)) and wish to reinvest all or a portion
of the redemption proceeds within 90 days of redemption can invest in Class A
shares without incurring a front-end sales charge. To qualify, shareholders must
notify their financial intermediary or the Transfer Agent in writing in advance
of reinvestment and must repurchase shares into an account with the same account
owner information. Please see REPURCHASES below for more information.

All other Class B share features, including but not limited to distribution and
service fees, CDSC and conversion features, will remain unchanged for Class B
shares held on and after the Effective Date.

CLASS C SHARES
New purchases of Class C shares will not be permitted if your rights of
accumulation are $1,000,000 or higher, except that there is no investment limit
on Class C shares purchased by employee benefit plans created under section
401(a), 401(k), 457 and 403(b), and qualified deferred compensation plans that
have a plan level or omnibus account maintained with the Fund or the Transfer
Agent and transacts directly with the Fund or the Transfer Agent through a third
party administrator or third party recordkeeper. See below under Rights of
Accumulation (ROA) below for information on rights of accumulation.

Class C shares have a higher annual distribution fee than Class A shares and a
CDSC for one year. Class C shares have no sales charge if you hold the shares
for longer than one year. Unlike Class B shares, Class C shares do not convert
to Class A shares. As a result, you will pay a distribution fee for as long as
you hold Class C shares.

The following information replaces the information under "Determining which
class of shares to purchase -- Class I Shares":

The following eligible investors may purchase Class I shares:

- - Any fund distributed by the Distributor, if the fund seeks to achieve its
  investment objective by investing in shares of the Funds.



Class I shares may be purchased, sold or exchanged only through the Distributor
or an authorized financial intermediary.

The following information replaces the information under "Determining which
class of shares to purchase -- Class R and Y Shares":

CLASS R SHARES (FORMERLY CLASS R2 SHARES)
Class R shares can only be bought through eligible health savings accounts
sponsored by third party platforms, including those sponsored by affiliates of
Ameriprise Financial, and the following eligible retirement plans: 401(k) plans;
457 plans; employer-sponsored 403(b) plans; profit sharing and money purchase
pension plans; defined benefit plans; and non-qualified deferred compensation
plans. Class R shares are not available for investment through retail

institutional investors.

CLASS R3, CLASS R4 AND CLASS R5 SHARES
CLASS R3, CLASS R4 AND CLASS R5 SHARES ARE CLOSED TO NEW INVESTORS AND NEW
ACCOUNTS EFFECTIVE AS OF THE CLOSE OF BUSINESS ON DECEMBER 31, 2010, SUBJECT TO
CERTAIN LIMITED EXCEPTIONS DESCRIBED BELOW.

the Fund as of the close of business on December 31, 2010 (including accounts

additional purchases of these share classes. Plans may continue to make
additional purchases of Fund shares and add new participants, and new plans
sponsored by the same or an affiliated sponsor may invest in the Fund (and add
new participants) if an initial plan so sponsored invested in the Fund as of
December 31, 2010 (or has approved the Fund as an investment option as of
December 31, 2010 and funds its initial account with the Fund prior to March 31,
2011) and holds Fund shares at the plan level.

In the event that an order to purchase Class R3, Class R4 or Class R5 shares is
received by the Fund or the Transfer Agent after the close of business on
December 31, 2010 from a new investor or a new account that is not eligible to
purchase shares, that order will be refused by the Fund and the Transfer Agent
and any money that the Fund or the Transfer Agent receives with the order will
be returned to the investor or the selling and/or servicing agent, as
appropriate, without interest.

Class R3, Class R4 and Class R5 shares are designed for qualified employee
benefit plans, trust companies or similar institutions, charitable organizations
that



meet the definition in Section 501(c)(3) of the Internal Revenue Code, non-
qualified deferred compensation plans whose participants are included in a
qualified employee benefit plan described above, state sponsored college savings
plans established under Section 529 of the Internal Revenue Code, and health
savings accounts created pursuant to public law 108-173. Additionally, if
approved by the Distributor, Class R5 shares are available to institutional or
corporate accounts above a threshold established by the Distributor (currently
$1 million per Fund or $10 million in all Funds) and bank trust departments.
Class R3, Class R4 and R5 shares may be purchased, sold or exchanged only
through the Distributor or an authorized selling and/or servicing agent. Class
R3, Class R4 shares and Class R5 shares of the Fund may be exchanged for Class
R3 shares, Class R4 shares and Class R5 shares, respectively, of another Fund.

(a) Purchase amounts and account values may be aggregated among all eligible
Fund accounts for the purposes of this table. See Rights of Accumulation (ROA)
for a discussion of account value aggregation.

(b) Because the offering price is calculated to two decimal places, the dollar
amount of the sales charge as a percentage of the offering price and your net
amount invested for any particular purchase of Fund shares



may be higher or lower depending on whether downward or upward rounding was
required during the calculation process. Purchase price includes the sales
charge.
(c) Although there is no sales charge for purchases with a total market value of
$1 million or more, and therefore no re-allowance, the Distributor may pay
selling and/or servicing agents the following out of its own resources: 1.00% on
purchases from $1 million up to but not including $3 million; 0.50% on purchases
of $3 million up to but not including $50 million; and 0.25% on amounts of $50
million or more. The Distributor may be reimbursed if a CDSC is deducted when
the shares are redeemed.
(d) For eligible employee benefit plans, selling and/or servicing agents are
eligible to receive from the Distributor the following sales commissions on
purchases that are coded as commission-eligible trades: 1.00% on all purchases
up to but not including $3 million, including those in amounts of less than $1
million; up to 0.50% on all purchases of $3 million up to but not including $50
million; and up to 0.25% on all purchases of $50 million or more.

CLASS A SHARES -- COMMISSIONS
The Distributor may pay your selling and/or servicing agent an up-front
commission when you buy Class A shares. The Distributor generally funds the
commission through the applicable sales charge paid by you. The up-front
commission on Class A shares, which varies by Fund, may be up to 5.00% of the
offering price for Funds with a maximum front-end sales charge of 5.75%, up to
4.00% of the offering price for Funds with a maximum front-end sales charge of
4.75%, up to 3.00% of the offering price for Funds with a maximum front-end
sales charge of 3.25%, up to 2.50% of the offering price for Funds with a
maximum front-end sales charge of 3.00%, and up to 0.75% of the offering price
for Funds with a maximum front-end sales charge of 1.00%.

The Distributor may also pay your selling and/or servicing agent a cumulative
commission when you buy $1 million or more of Class A shares, according to the
following schedule:

* Not applicable to RiverSource S&P 500 Index Fund.
** For eligible employee benefit plans, selling and/or servicing agents are
eligible to receive from the Distributor sales commissions on purchases (that
are coded as commission-eligible trades) in amounts of less than $1 million

The following information replaces the information under "Rights of Accumulation
(ROA)" and "Letter of Intent (LOI)":

There are two ways in which you may be able to reduce the front-end sales charge
that you may pay when you buy Class A, Class E or Class T shares of the Fund.
These types of sales charge reductions are also referred to as breakpoint
discounts.



First, through the right of accumulation (ROA), you may combine the value of
eligible accounts maintained by you and members of your immediate family to
reach a breakpoint discount level and apply a lower sales charge to your
purchase. To calculate the combined value of your accounts in the particular
class of shares, the Fund will use the current public offering price per share.
For purposes of obtaining a Class A shares breakpoint discount through ROA, you
may aggregate your or your family members' ownership of different classes of
shares, except for Class I, Class R, Class R3, Class R4, Class R5 and Class Y
shares, which may not be aggregated.

Second, by making a statement of intent to purchase additional shares (commonly
referred to as a letter of intent (LOI)), you may pay a lower sales charge on
all purchases (including existing ROA purchases) of Class A, Class E or Class T
shares made within 13 months of the date of your LOI. Your LOI must state the
aggregate amount of purchases you intend to make in that 13-month period, which
must be at least $50,000. The required form of LOI may vary by selling and/or
servicing agent, so please contact them directly for more information. Five
percent of the purchase commitment amount will be placed in escrow. At the end
of the 13-month period, the shares will be released from escrow, provided that
you have invested the commitment amount. If you do not invest the purchase
commitment amount by the end of the 13 months, the remaining amount of the
unpaid sales charge will be redeemed from the escrowed shares and the remaining
balance released from escrow. To calculate the total value of the purchases
you've made under an LOI, the Fund will use the historic cost (i.e., dollars
invested) of the shares held in each eligible account. For purposes of making an
LOI to purchase additional shares, you may aggregate your ownership of different
classes of shares, except for Class I, Class R, Class R3, Class R4, Class R5 and
Class Y shares, which may not be aggregated.

You must request the reduced sales charge (whether through ROA or an LOI) when
you buy shares. If you do not complete and file an LOI, or do not request the
reduced sales charge at the time of purchase, you will not be eligible for the
reduced sales charge. To obtain a breakpoint discount, you must notify your
financial advisor in writing at the time you buy your shares of each eligible
account maintained by you and members of your immediate family, including
accounts maintained through different financial advisors and selling and/or
servicing agents. You and your financial advisor are responsible for ensuring
that you receive discounts for which you are eligible. The Fund is not
responsible for a financial advisor's failure to apply the eligible discount to
your account. You may be asked by your financial advisor for account statements
or other records to verify your discount eligibility, including, when
applicable, records for accounts opened with a different financial advisor and
records of accounts established by members of your immediate family.



 YOUR "IMMEDIATE FAMILY" AND ACCOUNT VALUE AGGREGATION
 For purposes of obtaining a Class A shares breakpoint discount, the value of
 your account will be deemed to include the value of all applicable shares in
 eligible accounts that are held by you and your "immediate family," which
 includes your spouse, domestic partner, parent, step-parent, legal guardian,
 child, step-child, father-in-law and mother-in-law, provided that you and your
 immediate family members share the same mailing address. Any Fund accounts
 linked together for account value aggregation purposes as of the close of
 business on September 3, 2010 will be permitted to remain linked together.
 Remember that in order to obtain a breakpoint discount, you must notify your
 financial advisor in writing at the time you buy your shares of each eligible
 account maintained by you and members of your immediate family. Group plan
 accounts are valued at the plan level.

ELIGIBLE ACCOUNTS
The following accounts are eligible for account value aggregation as described
above:

- - Individual or joint accounts;

- - Roth and traditional Individual Retirement Accounts (IRAs), Simplified
  Employee Pension accounts (SEPs), Savings Investment Match Plans for Employees
  of Small Employers accounts (SIMPLEs) and Tax Sheltered Custodial Accounts

Class B, Class C, Class E, Class F, Class T, Class W and Class Z shares.

The following accounts are NOT eligible for account value aggregation as
described above:

- - Accounts of pension and retirement plans with multiple participants, such as
  401(k) plans (which are combined to reduce the sales charge for the entire
  pension or retirement plan and therefore are not used to reduce the sales
  charge for your individual accounts);



- - Accounts invested in Class I, Class R, Class R3, Class R4, Class R5 and Class
  Y shares;

- - Investments in 529 plans, donor advised funds, variable annuities, variable
  life insurance products, or managed separate accounts;

       acquisitions and exchange offers, to which the Funds are a party.

Restrictions may apply to certain accounts and certain transactions. The Funds
may change or cancel these terms at any time. Any change or cancellation applies
only to future purchases. Unless you provide your financial advisor with
information in writing about all of the factors that may count toward a waiver
of the sales charge, there can be no assurance that you will receive all of the
waivers for which you may be eligible. You should request that your financial
advisor provide this information to the Fund when placing your purchase order.
For more information about the sales charge reductions and waivers described
here, please see the SAI.

The following information replaces the information under "Class A -- contingent
deferred sales charge":

In some cases, you'll pay a CDSC if you sell Class A shares that you bought
without an initial sales charge.

     - If you bought Class A shares without an initial sales charge because your
       accounts aggregated between $1 million and $50 million at the time of
       purchase, you will incur a CDSC if you redeem those shares in accordance
       with the following policies:

          - Columbia fund shareholders who purchased shares of a Columbia fund
            on or before September 3, 2010 will incur a 1.00% CDSC if those
            shares are redeemed within one year of purchase.

          - Fund shareholders who purchased shares after September 3, 2010 will
            incur a CDSC if those shares are redeemed within 18 months of
            purchase, which is charged as follows: 1.00% CDSC if shares are
            redeemed within 12 months of purchase, and 0.50% CDSC if shares are
            redeemed more than 12, but less than 18, months after purchase.



     - Subsequent Class A share purchases that bring your aggregate account
       value to $1 million or more (but less than $50 million) will also be
       subject to a CDSC if you redeem them within the time periods noted
       immediately above.

For purposes of calculating the CDSC on shares of a Columbia fund and, for
shares of a RiverSource fund purchased after the close of business on September
3, 2010, the start of the holding period is the first day of the month in which
your purchase was made. For purposes of calculating the CDSC on shares of a
RiverSource fund purchased on or before the close of business on September 3,
2010, the start of the holding period is the date your purchase was made. When
you place an order to sell your Class A shares, the Fund will first redeem any
shares that aren't subject to a CDSC, followed by those you have held the
longest. This means that if a CDSC is imposed, you cannot designate the
individual shares being redeemed for federal income tax purposes. You should
consult your tax advisor about the tax consequences of investing in the Fund. In
certain circumstances, the CDSC may not apply.

The following information replaces the information under "CDSC -- Waivers of the
CDSC for Class A shares" and "CDSC -- Waivers of the CDSC for Class C shares":

CDSC -- Waivers of the CDSC for Class A and Class C shares.  The CDSC will be
waived on redemptions of shares:

- - in the event of the shareholder's death.

- - to which no sales commission or transaction fee was paid to an authorized
  selling and/or servicing agent at the time of purchase.

- - purchased through reinvestment of dividends and capital gain distributions.

- - in an account that has been closed because it falls below the minimum account
  balance.

- - that result from required minimum distributions taken from retirement accounts
  upon the shareholders attainment of age 70 1/2.

- - that result from returns of excess contributions made to retirement plans or
  individual retirement accounts, so long as the selling and/or servicing agent
  returns the applicable portion of any commission paid by the Distributor.

- - of Class A shares of a Fund initially purchased by an employee benefit plan.

- - other than Class A shares, of a Fund initially purchased by an employee
  benefit plan that are not connected with a plan level termination.

- - in connection with the Fund's Small Account Policy (as described below).

- - at a Fund's discretion, issued in connection with plans of reorganization,
  including but not limited to mergers, asset acquisitions and exchange offers,
  to which the Fund is a party.

- - by certain other investors as set forth in more detail in the SAI.



The following information replaces the information under "Class B and Class
C -- CDSC alternative -- For Class B":

CLASS B SHARES -- SALES CHARGES
Effective September 7, 2010, the RiverSource funds no longer accept investments
from new or existing investors in Class B shares, except for certain limited
transactions involving existing investors in Class B shares as described in more
detail below.

You don't pay a front-end sales charge when you buy Class B shares, but you may
pay a CDSC when you sell Class B shares.

The CDSC on Class B shares:

- - is applied to the net asset value at the time of your purchase or sale,
  whichever is lower,

- - will not be applied to any shares you receive through reinvested distributions
  or on any amount that represents appreciation in the value of your shares,
  income earned by your shares, or capital gains, and

- - generally declines each year until there is no sales charge for redeeming
  shares.

For purposes of calculating the CDSC on shares of a Columbia fund and, for
shares of a RiverSource fund purchased after the close of business on September
3, 2010, the start of the holding period is the first day of the month in which
your purchase was made. For purposes of calculating the CDSC on shares of a
RiverSource fund purchased on or before the close of business on September 3,
2010, the start of the holding period is the date your purchase was made. When
you place an order to sell your Class B shares, the Fund will first redeem any
shares that aren't subject to a CDSC, followed by those you have held the
longest. This means that if a CDSC is imposed, you cannot designate the
individual shares being redeemed for federal income tax purposes. You should
consult your tax advisor about the tax consequences of investing in the Funds.

CLASS B SHARES -- CDSC
You'll pay a CDSC if you sell Class B shares unless you qualify for a waiver of
the CDSC or the shares you're selling were bought through reinvested
distributions. See "CDSC -- Waivers of the CDSC for Class B shares" for details.
Also, you will not pay a CDSC on any amount that represents appreciation in the



value of your shares, income earned by your shares, or capital gains. The CDSC
you pay on Class B shares depends on how long you've held your shares:

* Because of rounding in the calculation, the actual CDSC you pay may be more or
less than the CDSC calculated using these percentages.
** For shares purchased in a RiverSource fund (other than a Seligman fund) on or
prior to June 12, 2009, the CDSC percentage for year three is 4%.

For purposes of calculating the CDSC on shares of a RiverSource fund purchased
after the close of business on September 3, 2010, the start of the holding
period is the first day of the month in which your purchase was made. For
purposes of calculating the CDSC on shares of a RiverSource fund purchased on or
before the close of business on September 3, 2010, the start of the holding
period is the date your purchase was made. When you place an order to sell your
Class B shares, the Fund will first redeem any shares that aren't subject to a
CDSC, followed by those you have held the longest. This means that if a CDSC is
imposed, you cannot designate the individual shares being redeemed for federal
income tax purposes. You should consult your tax advisor about the tax
consequences of investing in the Funds.

CLASS B SHARES -- COMMISSIONS
If you are an investor who purchased Class B shares prior to their closing
(except for certain limited transactions), although there was no front-end sales
charge for Class B shares when you bought Class B shares, the Distributor paid
an up-front commission directly to your selling and/or servicing agent when you
bought the Class B shares (a portion of this commission may, in turn, have been
paid to your financial advisor). This up-front commission, which varies across
the Funds, was up to 4.00% of the net asset value per share of Funds with a
maximum CDSC of 5.00% and up to 2.75% of the net asset value per share of Funds
with a maximum CDSC of 3.00%. The Distributor continues to seek to recover this
commission through distribution fees it receives under the Fund's distribution
plan and any applicable CDSC paid when you sell your shares.



CONVERSION OF CLASS B SHARES TO CLASS A SHARES
Class B shares purchased in a Columbia fund at any time, a RiverSource fund
(other than a Seligman fund) at any time, or a Seligman fund on or after June
13, 2009 automatically convert to Class A shares after you've owned the shares
for eight years. Class B shares originally purchased in a Seligman fund on or
prior to June 12, 2009 will convert to Class A shares in the month prior to the
ninth year of ownership. The conversion feature allows you to benefit from the
lower operating costs of Class A shares, which can help increase your total
returns from an investment in the Fund.

Class B shares purchased in a RiverSource fund (other than a Seligman fund)
prior to May 21, 2005 age on a calendar year basis. Class B shares purchased in
a Columbia fund at any time, Seligman fund at any time, or a RiverSource fund on
or after May 21, 2005 age on a daily basis. For example, a purchase made on
November 12, 2004 completed its first year on December 31, 2004 under calendar
year aging, but completed its first year on November 11, 2006 under daily aging.

The following rules apply to the conversion of Class B shares to Class A shares:

- - Class B shares are converted on or about the 15th day of the month that they
  become eligible for conversion.

- - Any shares you received from reinvested distributions on these shares
  generally will convert to Class A shares at the same time.

- - You'll receive the same dollar value of Class A shares as the Class B shares
  that were converted. Class B shares that you received from an exchange of
  Class B shares of another Fund will convert based on the day you bought the
  original shares.

- - No sales charge or other charges apply, and conversions are free from U.S.
  federal income tax.

The following information replaces the information under "CDSC -- Waivers of the
CDSC for Class B shares":

CDSC -- Waivers of the CDSC for Class B shares. The CDSC will be waived on
redemptions of shares:

- - in the event of the shareholder's death.

- - that result from required minimum distributions taken from retirement accounts
  upon the shareholders' attainment of age 70 1/2.

- - in connection with the Fund's Small Account Policy (as described below).

- - by certain other investors, including certain institutions as set forth in
  more detail in the SAI.

The following information is added as a new last paragraph to "Class B and Class
C -- CDSC alternative -- For Class C":

For purposes of calculating the CDSC on shares of a Columbia fund and, for
shares of a RiverSource fund purchased after the close of business on



September 3, 2010, the start of the holding period is the first day of the month
in which your purchase was made. For purposes of calculating the CDSC on shares
of a RiverSource fund purchased on or before the close of business on September
3, 2010, the start of the holding period is the date your purchase was made.
When you place an order to sell your Class C shares, the Fund will first redeem
any shares that aren't subject to a CDSC, followed by those you have held the
longest. This means that if a CDSC is imposed, you cannot designate the
individual shares being redeemed for federal income tax purposes. You should
consult your tax advisor about the tax consequences of investing in the Funds.

The information under "Methods of Purchasing Shares" is amended to reflect the
following:

As of the Effective Date, all references to telephone numbers of the Transfer
Agent are changed to 800.345.6611, except that to place orders by telephone,
please call the Transfer Agent at 800.422.3737. Have your account number and
social security number (SSN) or taxpayer identification number (TIN) available
when calling.

You or the financial advisor through which you buy shares may establish an

CLASS Z SHARES MINIMUM INVESTMENTS
There is no minimum initial investment in Class Z shares for the following
categories of eligible investors:

- - Any person investing all or part of the proceeds of a distribution, rollover
  or transfer of assets into a Columbia Management Individual Retirement
  Account, from any deferred compensation plan which was a shareholder of any of
  the funds of Columbia Acorn Trust (formerly named Liberty Acorn Trust) on
  September 29, 2000, in which the investor was a participant and through which
  the investor invested in one or more of the funds of Columbia Acorn Trust
  immediately prior to the distribution, transfer or rollover.

- - Any health savings account sponsored by a third party platform and any omnibus
  group retirement plan for which a financial intermediary or other entity
  provides services and is not compensated by the Fund for those services, other
  than in the form of payments for shareholder servicing or sub-accounting
  performed in place of the Transfer Agent.

- - Any investor participating in a wrap program sponsored by a financial
  intermediary or other entity that is paid an asset-based fee by the investor
  and that is not compensated by the Fund for those services, other than
  payments for shareholder servicing or sub-accounting performed in place of the
  Transfer Agent.

The minimum initial investment in Class Z shares for the following eligible
investors is $1,000:

- - Any individual retirement plan (assuming the eligibility criteria below are
  met) or group retirement plan that is not held in an omnibus manner for which
  a financial intermediary or other entity provides services and is not
  compensated by the Fund for those services, other than in the form of payments
  for shareholder servicing or subaccounting performed in place of the Transfer
  Agent.

- - Any person employed as of April 30, 2010 by the former investment manager,
  distributor or transfer agent of the Columbia funds is eligible to make new
  and subsequent purchases in the Class Z shares through an individual
  retirement account.

The minimum initial investment in Class Z shares for the following categories of
eligible investors is $2,000:

- - Any investor buying shares through a Columbia Management state tuition plan
  organized under Section 529 of the Internal Revenue Code.

- - Any shareholder (as well as any family member of a shareholder or person
  listed on an account registration for any account of the shareholder) of
  another fund distributed by the Distributor (i) who holds Class Z shares; (ii)
  who held Primary A shares prior to the share class redesignation of Primary A
  shares as Class Z shares that occurred on August 22, 2005; (iii) who holds
  Class A shares that were obtained by an exchange of Class Z shares; or (iv)
  who



  bought shares of certain mutual funds that were not subject to sales charges
  and that merged with a Columbia fund distributed by the Distributor.

- - Any trustee or director (or family member of a trustee or director) of a fund
  distributed by the Distributor.

- - Any investor participating in an account offered by a financial intermediary
  or other entity that provides services to such an account, is paid an asset-
  based fee by the investor and is not compensated by the Fund for those
  services, other than payments for shareholder servicing or sub-accounting
  performed in place of the Transfer Agent (each investor buying shares through
  a financial intermediary must independently satisfy the minimum investment
  requirement noted above).

- - Any institutional investor who is a corporation, partnership, trust,
  foundation, endowment, institution, government entity, or similar
  organization, which meets the respective qualifications for an accredited
  investor, as defined under the Securities Act of 1933.

- - Certain financial institutions and intermediaries, such as insurance
  companies, trust companies, banks, endowments, investment companies or
  foundations, buying shares for their own account, including Ameriprise
  Financial and its affiliates and/or subsidiaries.

- - Any person employed as of April 30, 2010 by the former investment manager,
  distributor or transfer agent of the Columbia funds is eligible to make new
  and subsequent purchases in the Class Z shares through a non-retirement
  account.

- - Certain other investors as set forth in more detail in the SAI.

The minimum initial investment requirements for the classes of shares may be
waived for accounts that are managed by an investment professional, for accounts
held in approved discretionary or non-discretionary wrap programs, for accounts
that are a part of an employer-sponsored retirement plan, or for other account
types if approved by the Distributor.

The Fund reserves the right to modify its minimum investment and related
requirements at any time, with or without prior notice.

With respect a Medallion Signature Guarantee, as of the Effective Date, the
dollar threshold triggering the need for a Medallion Signature Guarantee is
increased from an amount greater than $50,000 to an amount greater than
$100,000. The following information replaces the information relating to how to
obtain a Medallion Signature Guarantee:

Qualified customers can obtain a Medallion Signature Guarantee from any
financial institution -- including commercial banks, credit unions and
broker/dealers -- that participates in one of the three Medallion signature
guarantee programs recognized by the Securities and Exchange Commission. These
Medallion Signature Guarantee programs are the Securities Transfer Agents
Medallion Program (STAMP), the Stock Exchanges Medallion Program (SEMP)



and the New York Stock Exchange Medallion Signature Program (MSP). Please note
that a guarantee from a notary public is not acceptable.

As of the Effective Date, the following limits are applicable:

You can sell up to and including an aggregate of $100,000 of Fund shares via the
telephone per day, per Fund, if you qualify for telephone orders. Wire
redemptions requested via the telephone are subject to a maximum of $3 million
of Fund shares per day, per Fund. You can buy up to and including $100,000 of
Fund shares per day, per Fund through your bank account as an Automated Clearing
House (ACH) transaction via the telephone if you qualify for telephone orders.

The following is hereby added under "Methods of Purchasing Shares":

ONLINE TRANSACTIONS
Once Class A, Class B, Class C, Class R, Class Y and Class Z shareholders have
an account, they may contact the Transfer Agent at 800.345.6611 for more
information on account trading restrictions and the special sign-up procedures
required for online transactions. The Transfer Agent has procedures in place to
authenticate electronic orders you deliver through the internet. You will be
required to accept the terms of an online agreement and to establish and utilize
a password in order to access online account services. You can sell up to and
including an aggregate of $100,000 of Fund shares per day, per Fund account
through the internet if you qualify for internet orders.

IMPORTANT:
Payments sent by electronic fund transfers, a bank authorization, or check that
are not guaranteed may take up to 14 days to clear. If you request a redemption
within 14 days of purchase, this may cause your redemption request to fail to
process if the requested amount includes unguaranteed funds. Proceeds from
purchases by check or from a bank account as an Automated Clearing House (ACH)
transaction will be held when you sell those shares for up to 10 days after the
trade date of the purchase.

SYSTEMATIC WITHDRAWAL PLAN
The Systematic Withdrawal Plan lets you withdraw funds from your Class A, Class
B, Class C, Class  I, Class W, Class Y and/or Class Z shares account any day of
the month on a monthly, quarterly or semi-annual basis. Contact the Transfer
Agent or your financial advisor to set up the plan. To set up the plan, your
account balance must meet the Fund Class' minimum initial investment amount. All
dividend and capital gain distributions must be reinvested to set up the plan. A
Systematic Withdrawal Plan cannot be set up on an account that already has a
Systematic Investment Plan established. If you set up the plan after you've
opened your account, we may require your signature to be Medallion Signature
Guaranteed.



You can choose to receive your withdrawals via check or direct deposit into your
bank account. Otherwise, the Fund will deduct any applicable CDSC from the
withdrawals before sending the balance to you. You can cancel the plan by giving
the Fund 30 days notice in writing or by calling the Transfer Agent at
800.422.3737. It's important to remember that if you withdraw more than your
investment in the Fund is earning, you'll eventually use up your original
investment.

SMALL ACCOUNT POLICY -- CLASS A, B, C, T AND Z SHARE ACCOUNTS MINIMUM BALANCE
FEE
If the value of your Fund account (treating each account of the Fund you own
separately from any other account of the Fund you may own) falls below the
minimum initial investment requirement applicable to you for any reason,
including as a result of market decline, your account generally will be subject
to a $20 annual fee. This fee will be assessed through the automatic sale of
shares in your Fund account. Any otherwise applicable CDSC will not be imposed
on such an automatic sale of your shares. The Transfer Agent will reduce the
expenses paid by the Fund by any amounts it collects from the assessment of this
fee. For Funds that do not have transfer agency expenses against which to offset
the amount collected through assessment of this fee, the fee will be paid
directly to the Fund. The Transfer Agent will send you written notification in
advance of assessing any fee, which will provide details on how you can avoid
the imposition of such fee. Generally, you may avoid the imposition of such fee
by raising your account balance, consolidating your accounts through an exchange
of shares of another Fund in which you hold shares, or setting up a Systematic
Investment Plan. For more information, contact the Transfer Agent or your
financial advisor.

Each Fund reserves the right to change its minimum investment requirements. The
Funds also reserve the right to lower the account size trigger point for the
minimum balance fee in any year or for any class of shares when we believe it is
appropriate to do so in light of declines in the market value of Fund shares,
sales loads applicable to a particular class of shares, or for other reasons.

EXCEPTIONS TO THE ABOVE SMALL ACCOUNT POLICY (Accounts Below $250 and Minimum
Balance Fee)
The automatic sale of shares of accounts under $250 and the annual minimum
balance fee described previously do not apply to shareholders of Class E, Class
F, Class R, Class R3, Class R4, Class R5, Class Y and Class W shares or
shareholders holding their shares through broker/dealer networked accounts; wrap
fee and omnibus accounts; accounts with active Systematic Investment Plans; and
certain qualified retirement plans and health savings accounts. The automatic
sale of shares of accounts under $250 does not apply to individual retirement
plans.



SMALL ACCOUNT POLICY -- BROKER/DEALER AND WRAP FEE ACCOUNTS
The Funds may automatically redeem at any time broker/dealer networked accounts
and wrap fee accounts that have account balances of $20 or less or have less
than one share.

DIVIDEND DIVERSIFICATION
Generally, you may automatically invest distributions made by another Fund into
the same class of shares (and in some cases certain other classes of shares) of
the Fund at no additional sales charge. A sales charge may apply when you invest
distributions made with respect to shares that were not subject to a sales
charge at the time of your initial purchase.

SYSTEMATIC EXCHANGES
You may buy Class A, Class B, Class C, Class T, Class W, Class Y and/or Class Z
shares of a Fund by exchanging each month from another Fund for shares of the
same class of the Fund at no additional cost, subject to the following exchange
amount minimums: $50 each month for individual retirement accounts (i.e. tax
qualified accounts); and $100 each month for non-retirement accounts. Contact
the Transfer Agent or your financial advisor to set up the plan. If you set up
your plan to exchange more than $100,000 each month, you must obtain a Medallion
Signature Guarantee.

Exchanges will continue as long as your balance is sufficient to complete the
systematic monthly transfers, subject to the Funds' Small Account Policy
described above. You may terminate the program or change the amount you would
like to exchange (subject to the $50 and $100 minimum requirements noted
immediately above) by calling the Funds at 800.345.6611. A sales charge may
apply when you exchange shares of a Fund that were not assessed a sales charge
at the time of your initial purchase.

SAME-FUND EXCHANGE PRIVILEGE FOR CLASS Z SHARES
Certain shareholders invested in a class of shares other than Class Z may become
eligible to invest in Class Z shares. Upon a determination of such eligibility,
any such shareholders will be eligible to exchange their shares for Class Z
shares of the same Fund, if offered. No sales charges or other charges will
apply to any such exchange, except that when Class B shares are exchanged for
Class Z shares, any CDSC charges applicable to Class B shares will be applied.
Ordinarily, shareholders will not recognize a gain or loss for federal income
tax purposes upon such an exchange. Investors should contact their selling and/
or servicing agents to learn more about the details of the Class Z shares
exchange privilege.

OTHER REDEMPTION RULES YOU SHOULD KNOW
- - Once the Transfer Agent or your selling and/or servicing agent receives your
  sell order in "good form," your shares will be sold at the next calculated net



  asset value per share. Any applicable CDSC will be deducted from the amount
  you're selling and the balance will be remitted to you.

- - If you sell your shares directly through the Funds, we will normally send the
  sale proceeds by mail or electronically transfer them to your bank account
  within three business days after the Transfer Agent or your selling and/or
  servicing agent receives your order in "good form."

- - If you sell your shares through a selling agent, the Funds will normally send
  the sale proceeds by Fedwire within three business days after the Transfer
  Agent or your selling and/or servicing agent receives your order in "good
  form."

- - If you paid for your shares by check or from your bank account as an Automated
  Clearing House (ACH) transaction, the Funds will hold the sale proceeds when
  you sell those shares for a period of time after the trade date of the
  purchase.

- - No interest will be paid on uncashed redemption checks.

- - The Funds can delay payment of the sale proceeds for up to seven days and may
  suspend redemptions and/or postpone payment of redemption proceeds when the
  NYSE is closed or during emergency circumstances as determined by the SEC.

- - Other restrictions may apply to retirement accounts. For information about
  these restrictions, contact your retirement plan administrator.

- - Also keep in mind the Funds' Small Account Policy.

The following information replaces the information under and including the
caption heading "Other exchange policies":

OTHER EXCHANGE RULES YOU SHOULD KNOW
- - Exchanges are made at net asset value next calculated after your exchange
  order is received in good form.

- - Once the Fund receives your exchange request, you cannot cancel it after the
  market closes.

- - The rules for buying shares of a Fund generally apply to exchanges into that
  Fund, including, if your exchange creates a new account, it must satisfy the
  minimum investment amount for new purchases, unless a waiver applies.

- - Shares of the purchased Fund may not be used on the same day for another
  exchange or sale.

- - You can generally make exchanges between like share classes of any Fund. Some
  exceptions apply.

- - If you exchange shares from Class A shares of a money market Fund to a non-
  money market Fund, any further exchanges must be between shares of the same
  class. For example, if you exchange from Class A shares of a money market Fund
  into Class C shares of an equity Fund, you may not exchange



  from Class C shares of that equity Fund back to Class A shares of a money
  market Fund.

- - A sales charge may apply when you exchange shares of a Fund that were not
  assessed a sales charge at the time of your initial purchase. If your initial
  investment was in a money market Fund and you exchange into an equity or fixed
  income Fund, your transaction is subject to a front-end sales charge if you
  exchange into Class A shares and the CDSC if you exchange into Class C, Class
  E, Class F and Class T shares of the Funds.

- - If your initial investment was in Class A shares of an equity Fund or fixed
  income Fund and you exchange shares into a money market Fund, you may exchange
  that amount to another Fund, including dividends earned on that amount,
  without paying a sales charge.

- - If your shares are subject to a CDSC, you will not be charged a CDSC upon the
  exchange of those shares. Any CDSC will be deducted when you sell the shares
  you received from the exchange. The CDSC imposed at that time will be based on
  the period that begins when you bought shares of the original Fund and ends
  when you sell the shares of the Fund you received from the exchange. The
  applicable CDSC will be the CDSC of the original Fund.

- - You may make exchanges only into a Fund that is legally offered and sold in
  your state of residence. Contact the Transfer Agent or your financial advisor
  for more information.

- - You generally may make an exchange only into a Fund that is accepting
  investments.

- - The Fund may change or cancel your right to make an exchange by giving the
  amount of notice required by regulatory authorities (generally 60 days for a
  material change or cancellation).

- - Unless your account is part of a tax-advantaged arrangement, an exchange for
  shares of another Fund is a taxable event, and you may recognize a gain or
  loss for tax purposes.

- - Shares of Class W originally purchased, but no longer held in a discretionary
  managed account, may not be exchanged for Class W shares of another Fund. You
  may continue to hold these shares in the original Fund. Changing your
  investment to a different Fund will be treated as a sale and purchase, and you
  will be subject to applicable taxes on the sale and sales charges on the
  purchase of the new Fund.

The following information replaces the information under "Check Redemption
Service":

Effective September 7, 2010, only Class A shares of the money market Funds offer
check writing privileges. If you have $2,000 in a money market Fund, you may
request checks which may be drawn against your account. The amount of any check
drawn against your money market Fund must be at least $100. You can elect this
service on your initial application or thereafter. Call 800.345.6611



for the appropriate forms to establish this service. If you own Class A shares
that were both in another Fund at NAV because of the size of the purchase, and
then exchanged into a money market Fund, check redemptions may be subject to a
CDSC. A $15 charge will be assessed for any stop payment order requested by you
or any overdraft in connection with checks written against your money market
Fund account.

The following information replaces the information under "Short-Term or
Excessive Trading":

EXCESSIVE TRADING PRACTICES POLICY OF NON-MONEY MARKET FUNDS
Right to Reject or Restrict Share Transaction Orders -- The Fund is intended for
investors with long-term investment purposes and is not intended as a vehicle
for frequent trading activity (market timing) that is excessive. Investors
should transact in Fund shares primarily for investment purposes. The Board has
adopted excessive trading policies and procedures that are designed to deter
excessive trading by investors (the Excessive Trading Policies and Procedures).
THE FUND DISCOURAGES AND DOES NOT ACCOMMODATE EXCESSIVE TRADING.

The Fund reserves the right to reject, without any prior notice, any buy or
exchange order for any reason, and will not be liable for any loss resulting
from rejected orders. For example, the Fund may in its discretion restrict or
reject a buy or exchange order even if the transaction is not subject to the
specific exchange limitation described below if the Fund or its agents determine
that accepting the order could interfere with efficient management of the Fund's
portfolio or is otherwise contrary to the Fund's best interests. The Excessive
Trading Policies and Procedures apply equally to buy or exchange transactions
communicated directly to the Transfer Agent and to those received by selling
and/or servicing agents.

Specific Buying and Exchanging Limitations -- If a Fund detects that an investor
has made two "material round trips" in any 28-day period, it will generally
reject the investor's future buy orders, including exchange buy orders,
involving any Fund.

For these purposes, a "round trip" is a purchase or exchange into the Fund
followed by a sale or exchange out of the Fund, or a sale or exchange out of the
Fund followed by a purchase or exchange into the Fund. A "material" round trip
is one that is deemed by the Fund to be material in terms of its amount or its
potential detrimental impact on the Fund. Independent of this limit, the Fund
may, in its discretion, reject future buy orders by any person, group or account
that appears to have engaged in any type of excessive trading activity.

These limits generally do not apply to automated transactions or transactions by
registered investment companies that invest in the Fund using a "fund of funds"
structure. These limits do not apply to payroll deduction contributions by
retirement plan participants, transactions initiated by a retirement plan
sponsor or



certain other retirement plan transactions consisting of rollover transactions,
loan repayments and disbursements, and required minimum distribution
redemptions. They may be modified or rescinded for accounts held by certain
retirement plans to conform to plan limits, for considerations relating to the
Employee Retirement Income Security Act of 1974 or regulations of the Department
of Labor, and for certain asset allocation or wrap programs. Accounts known to
be under common ownership or control generally will be counted together, but
accounts maintained or managed by a common intermediary generally will not be
considered to be under common ownership or control. The Fund retains the right
to modify these restrictions at any time without prior notice to shareholders.

Limitations on the Ability to Detect and Prevent Excessive Trading
Practices -- The Fund takes various steps designed to detect and prevent
excessive trading, including daily review of available shareholder transaction
information. However, the Fund receives buy, sell and exchange orders through
selling and/or servicing agents, and cannot always know of or reasonably detect
excessive trading that may be facilitated by selling and/or servicing agents or
by the use of the omnibus account arrangements they offer. Omnibus account
arrangements are common forms of holding shares of mutual funds, particularly
among certain selling and/or servicing agents such as broker/dealers, retirement
plans and variable insurance products. These arrangements often permit selling
and/or servicing agents to aggregate their clients' transactions and accounts,
and in these circumstances, the identity of the shareholders is often not known
to the Fund.

Some selling and/or servicing agents apply their own restrictions or policies to
underlying investor accounts, which may be more or less restrictive than those
described here. This may impact the Fund's ability to curtail excessive trading,
even where it is identified. For these and other reasons, it is possible that
excessive trading may occur despite the Fund's efforts to detect and prevent it.

Although these restrictions and policies involve judgments that are inherently
subjective and may involve some selectivity in their application, the Fund seeks
to act in a manner that it believes is consistent with the best interests of
shareholders in making any such judgments.

Risks of Excessive Trading -- Excessive trading creates certain risks to the
Fund's long-term shareholders and may create the following adverse effects:

- - negative impact on the Fund's performance;

- - potential dilution of the value of the Fund's shares;

- - interference with the efficient management of the Fund's portfolio, such as
  the need to maintain undesirably large cash positions, the need to use its
  line of credit or the need to buy or sell securities it otherwise would not
  have bought or sold;

- - losses on the sale of investments resulting from the need to sell securities
  at less favorable prices;



- - increased taxable gains to the Fund's remaining shareholders resulting from
  the need to sell securities to meet sell orders; and

- - increased brokerage and administrative costs.

To the extent that the Fund invests significantly in foreign securities traded
on markets that close before the Fund's valuation time, it may be particularly
susceptible to dilution as a result of excessive trading. Because events may
occur after the close of foreign markets and before the Fund's valuation time
that influence the value of foreign securities, investors may seek to trade Fund
shares in an effort to benefit from their understanding of the value of foreign
securities as of the Fund's valuation time. This is often referred to as price
arbitrage. The Fund has adopted procedures designed to adjust closing market
prices of foreign securities under certain circumstances to reflect what the
Fund believes to be the fair value of those securities as of its valuation time.
To the extent the adjustments don't work fully, investors engaging in price
arbitrage may cause dilution in the value of the Fund's shares held by other
shareholders.

Similarly, to the extent that the Fund invests significantly in thinly traded
high-yield bonds (junk bonds) or equity securities of small-capitalization
companies, because these securities are often traded infrequently, investors may
seek to trade their shares in an effort to benefit from their understanding of
the value of these securities. This is also a type of price arbitrage. Any such
frequent trading strategies may interfere with efficient management of the
Fund's portfolio to a greater degree than would be the case for mutual funds
that invest in highly liquid securities, in part because the Fund may have
difficulty selling those portfolio securities at advantageous times or prices to
satisfy large and/or frequent sell orders. Any successful price arbitrage may
also cause dilution in the value of Fund shares held by other shareholders.

EXCESSIVE TRADING PRACTICES POLICY OF MONEY MARKET FUNDS
The money market Funds are designed to offer investors a liquid cash option that
they may buy and sell as often as they wish. Accordingly, the Board has not
adopted policies and procedures designed to discourage excessive or short-term
trading of money market Fund shares. However, since frequent purchases and sales
of money market Fund shares could in certain instances harm shareholders in
various ways, including reducing the returns to long-term shareholders by
increasing costs (such as spreads paid to dealers who trade money market
instruments with the money market Funds) and disrupting portfolio management
strategies, each of the money market Funds reserves the right, but has no
obligation, to reject any buy or exchange transaction at any time. Except as
expressly described in this prospectus (such as minimum purchase amounts), the
money market Funds have no limits on buy or exchange transactions. In addition,
each of the money market Funds reserve the right to impose or modify
restrictions on purchases, exchanges or trading of the Fund shares at any time.



The following information replaces the information under "Repurchases":

Investors can also buy Class A shares without paying a sales charge if the
purchase is made from the proceeds of a redemption from any Class A, B, C or T
shares within 90 days, up to the amount of the redemption proceeds. Any CDSC
paid upon redemption of your Class A, B, C or T shares will not be reimbursed.
If your original purchase was in Class T shares, you will be allowed to reinvest
in the same Class T shares account and Fund you originally purchased.

After the close of business on September 3, 2010, RiverSource fund shareholders
may not invest or reinstate their investment in Class B shares of a RiverSource
fund. However, shareholders who redeem Class B shares and wish to reinvest all
or a portion of the redemption proceeds within 90 days of redemption can invest
in Class A shares without incurring a front-end sales charge. To qualify,
shareholders must notify their financial advisor or the Transfer Agent in
writing in advance of reinvestment and must purchase shares into an account with
the same account owner information.

To be eligible for these reinstatement privileges the purchase must be made into
an account for the same owner, but does not need to be into the same Fund from
which the shares were sold. The Transfer Agent, the Distributor or their agents
must receive a written reinstatement request from you or your selling and/or
servicing agent within 90 days after the shares are redeemed and the purchase of

Class A shares through this reinstatement privilege will be made at the NAV of
such shares next calculated after the request is received in good order.
Systematic withdrawals and purchases are excluded from this policy.

The last sentence of the fourth paragraph under "Pricing and Valuing of Fund

The following information replaces the information under and including the
section heading "PAYMENTS TO FINANCIAL INTERMEDIARIES":

FINANCIAL INTERMEDIARY COMPENSATION
The Distributor and the investment manager make payments, from their own
resources, to certain financial intermediaries, including selling and/or
servicing agents, including other Ameriprise Financial affiliates, for
marketing/sales support services relating to the Funds. Such payments are
generally based upon one or more of the following factors: average net assets of
the Funds sold by the Distributor attributable to that intermediary, gross sales
of the Funds distributed by the Distributor attributable to that intermediary,
reimbursement of ticket charges (fees that a selling and/or servicing agent
charges its representatives for effecting transactions in Fund shares) or a
negotiated lump sum payment. While the financial arrangements may vary for each
intermediary, the support payments



to any one intermediary are generally between 0.05% and 0.50% on an annual basis
for payments based on average net assets of the Fund attributable to the
intermediary, and between 0.05% and 0.25% on an annual basis for firms receiving
a payment based on gross sales of the Funds attributable to the intermediary.

The Distributor and the investment manager may make payments in larger amounts
or on a basis other than those described above when dealing with certain
financial intermediaries. Such increased payments may enable such financial
intermediaries to offset credits that they may provide to customers.

The Distributor, the Transfer Agent and the investment manager may also make
payments to financial intermediaries, including other Ameriprise Financial
affiliates, that provide shareholder services to retirement plans and other
investment programs to compensate those intermediaries for services they provide
to such programs, including, but not limited to, sub-accounting, sub-transfer
agency, similar shareholder or participant recordkeeping, shareholder or
participant reporting, or shareholder or participant transaction processing. The
Distributor and the Advisor may make payments in larger amounts or on a basis
other than those described above when dealing with certain affiliates of Bank of
America Corporation (Bank of America). Such increased payments to the Bank of
America affiliates may enable the Bank of America affiliate to offset credits
that it may provide to customers.

These payments for shareholder servicing support vary by financial intermediary
but generally are not expected, with certain limited exceptions, to exceed 0.40%
of the average aggregate value of the Fund's shares in any intermediary's
program on an annual basis for those classes of shares that pay a service fee
pursuant to a plan under Rule 12b-1 under the 1940 Act, and 0.45% of the average
aggregate value of the Fund's shares in any intermediary's program on an annual
basis for those classes of shares that do not pay a service fee pursuant to a
plan under Rule 12b-1 under the 1940 Act.

For all classes other than Class Y shares, the Funds may reimburse the Transfer
Agent for amounts paid to financial intermediaries that maintain assets in
omnibus accounts, subject to an annual cap that varies among Funds. Generally,
the annual cap for each Columbia fund (other than the Columbia Acorn funds) and
each RiverSource fund is 0.20% of the average aggregate value of the Fund's
shares maintained in such accounts for financial intermediaries that seek
payment by the Transfer Agent based on a percentage of net assets. Please see
the SAI for additional information. The annual cap for Columbia Acorn funds is
0.05% of the average aggregate value of the Fund's shares maintained in such
accounts. The amounts in excess of that reimbursed by the Fund are borne by the
Distributor or the investment manager. The Distributor and the investment
manager may make other payments or allow promotional incentives to broker/



dealers to the extent permitted by SEC and Financial Industry Regulatory
Authority (FINRA) rules and by other applicable laws and regulations.

Amounts paid by the Distributor and the investment manager and their affiliates
are paid out of the Distributor's and the investment manager's own resources and
do not increase the amount paid by you or the Fund. You can find further details
about the payments made by the Distributor and the investment manager and their
affiliates and the services provided by financial intermediaries as well as a
list of the intermediaries, including Ameriprise Financial affiliates, to which
the Distributor and the investment manager have agreed to make marketing support
payments in the SAI. Your financial intermediary may charge you fees and
commissions in addition to those described in this prospectus. You should
consult with your financial intermediary and review carefully any disclosure
your financial intermediary provides regarding its services and compensation.
Depending on the financial arrangement in place at any particular time, a
financial intermediary and its financial consultants may have a financial
incentive for recommending the Fund or a particular share class over others.
